MotorPower Care Catalytic Converter Cleaner Kit — 2‑Part tank additive + O2‑port foam spray for soot and carbon removal

MotorPower Care Catalytic Converter Cleaner Kit is a two-part, new-technology system that cleans and helps restore catalytic function using a tank additive and a targeted foam spray applied through the O2 sensor port.

This kit combines a fuel-system additive and a direct foam cleaner to remove soot, carbon and light deposits inside catalytic converters without disassembly. Designed by MotorPower Care, the products are formulated for use in petrol, diesel and hybrid vehicles. For safety and best results, inspect the catalyst housing for visible cracks or damage before using the cleaner; a physically broken catalyst cannot be repaired by a chemical treatment.

How does the two-step system work to clean a clogged catalyst?

The kit uses complementary actions: the tank additive treats deposits upstream in the fuel system and combustion chamber, reducing soot formation, while the foam spray penetrates and loosens deposits directly on the catalyst substrate via the O2 sensor port. Together they target both the source and the buildup, helping restore gas flow and reduce blockage-related symptoms.

• Tank additive mixes with fuel to reduce deposit formation during combustion.
• Foam spray applied through the O2 sensor port reaches the catalyst internals.
• Combined use addresses both upstream sources and the converter surface buildup.

Will this kit fix P0420 or P0430 fault codes?

The cleaner can resolve catalyst-efficiency codes (P0420/P0430) when the issue is caused by carbon or soot deposits rather than physical damage or substrate breakdown. If the internal honeycomb is cracked or the catalyst materials have deteriorated, a chemical cleaner will not clear the code; diagnostic inspection is recommended first.

• Effective on codes caused by light-to-moderate deposit buildup.
• Not effective for mechanically damaged or thermally degraded catalysts.
• Always scan and inspect before treatment to confirm suitability.

How do I apply each product safely and correctly?

Start by following the included instructions: add the measured tank treatment to your fuel tank, then run the engine to circulate the additive. For the foam cleaner, remove the appropriate oxygen sensor or access plug and carefully introduce the spray into the catalyst port per directions, using protective equipment and working in a ventilated area.

• Inspect the catalyst housing for cracks before applying any chemicals.
• Use the correct O2 port or access point; avoid force or incorrect fittings.
• Wear gloves and eye protection; perform spray steps outdoors or in a ventilated bay.

How long until I notice performance or emissions changes?

Some drivers see improved responsiveness, reduced exhaust smell or cleared fault codes after one full treatment cycle; others require repeated applications over a few hundred kilometers to dislodge heavier deposits. Results depend on deposit severity, engine condition and driving patterns, so allow time and re-check diagnostics after treatment.

• Light buildups may respond after a single treatment and short driving session.
• Heavier sooting may need repeated treatments and road use to clear fully.
• Follow-up OBD scans confirm whether codes have cleared or further action is needed.

Who is this for: The MotorPower Care kit is aimed at DIY mechanics, professional technicians and vehicle owners who want a cost-effective alternative to catalytic converter removal or replacement when deposits—not physical damage—are the root cause. It suits petrol, diesel and hybrid cars, vans and light trucks that show reduced performance, mild exhaust restriction or efficiency-related OBD codes; it is not a repair for mechanically broken converters.
